Pulmonary hypertension associated with chronic respiratory disease. Cardiology, 95pp. For those with very severe disease, surgery is sometimes helpful and may include lung transplantation or lung volume-reduction surgery which involves removing the parts of the lung most damaged by emphysema, allowing the remaining, relatively good lung to expand and work better.

Retrieved 4 March Role of HIF-1alpha in hypoxia-mediated apoptosis, cell proliferation and tumour angiogenesis. The rate at which COPD worsens varies with the presence of factors that predict a poor outcome, including severe airflow obstruction, little ability to exercise, shortness of breath, significant underweight or overweight, congestive heart failurecontinued smoking, and frequent exacerbations.
